To alljwhom it may concern:

Beit known that I, GEORGE H. onsr'rii, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Cushions, of which the following is a specification, this application being Va division of m copending application, Serial No. 459, 75, filed October 27, 19GB. K l

This invention relates to metalA constructions which are more particularly, though not exclusively, designed for use in railway cars, the object of the invention being the provision in connection with a car window sashof cushioning means whereby to aHord a resilient abutment as the sash is lowered,

to edectually exclude the elements, and to adapt the lower sashl edge to the variations in conformation of the window sill, and a special object 'of the invention being improved means of assembling and retaining the cushion in place in the sash.

In the accompanying drawing is set forth in transverse vertical section a fragmentary portionof a sash with the cushioning strip assembled in preferred relation. thereto. As,

however, certain modiications are practicable without departure from the essence of the invention or the material sacrifice of its advantages it is to be' understood that the drawing and the description based thereon are to be taken in an illustrative and not in an unnecessarily limiting sense.

Referring to the drawing, 11 designates the usual inside window sill and 12 the offset inclosed outer sill upon which and bearing against the verticalwall 13 of the offset rests the window sash indicated generally at la. In mamng up the stile and rails from the sash members I take a pair of sheet metal strips that are bent longitudinally to the substantially duplicate cross-sectional form shown in the drawing, each member forming an outer side wall 15 of the stile,

' a glazing bead 16, andthe side walls 17 of a rentrant groove inthe outer edgeof the stile the meeting margin of the strips being over apped as shown, to form transverse walls of double thickness for the bottoms 18 and 19 of the glass-receiving groove and the said rentrant groove, respectively. The two longitudinal halves of the stile thus formed and joined are secured together by a longitudinally bent clamp-strip 20 which is sol shaped as to'embrace the side walls l5 preferably under tension and also enter and iit the rentrant groove in the outer edge of the-stile; and the side walls 15, together with the margins of the clamp-strip 20 are securely united by transverse pins 21 that are surrounded by spacing sleeves 22, which. latter are somewhat less in length than the distance between the inner sides of the walls 15, thereby permitting the latter to be drawn together to cause the beads 16 to snugly grip the` glass indicated at 23, a rub. ber or other resilient pacln'ng strip 24 being fitted to the edge of the glass. I

In the rentrant groove on the bottom of the sash I mount a novel cushioning member for the sash, the same consisting of a strip 25 of yielding material, preferably rubber, which preferably is formed with a longitudinally channeled or transversely, concave lower face 26 which adapts the saine to a close fit on sills having different degrees of transverse inclination, and also adapts groove ofthe sash-bar and is preferably embraced by a channel-shaped metal clip 28 f yslidably mounted within the groove and having inwardly turned margins 29 which bite into the neck of the tongue and securely grip the latter. The upper corners of the clip 28 are rounded, as shown, oppositethel corners of the rentrant groove in order to avoid any interference withthe transverse compressibility of the sash-bar. The clip 28 is readily insertible in the groove and is held therein frictionally and also by the clamping action of the clamp strip 20 under the tension of the pins 21.

1. rlhe combination with a sash member, having in its lower edge a rentrant groove, of a rubber cushion having its lower face longitudinally channeled and its upper face provided with a longitudinal tongue, a metallic clip engaging the tongue of the' cushion and slidably mounted within the sash groove, and means to clamp the walls of the rentranty groove upon the clip, substantially as described.

2. The combination with a hollow longi-` tudinally divided metal sash bar having a rentrant groove in its lower edge, of a cushioning strip having a tongue adapted to enter said channel, a hollow metal clamp in said channel embracing said tongue and provided with inturned edges adapted to grip the neck of the latter, and meansfor compressing the sides of 'said channel on said clamp and tongue comprising transverse tensioning members, substantially 'as described.

3. A window sash 'having along its inner edge a glazing groove, said sash comprising two sections separable in the plane of the sash and groove, and releasable means to removably secure the two sections together upon the glass seated in the groove.

4. `A window sash having along its inner edge a glazing groove and along its outer edge a cushion-retaining groove, said sash comprisingl two sections separable in the plane of the sash' and grooves, and releasable means to removably secure the two sections together upon the glass and cushion seated in the respective grooves.

I 5. The combination with a sash, of a cushion for the lower, rail thereof, rsai cushion comprising a bodyl portion dispose beneath the lower face ofl the sash rail and having a lower marginally lipped portion, the cushion body supported directly above the lipped portion by the said lower face of the sash.

6. The combination with a sash, of a cushion for the` grooved lower rail thereof, said. cushion comprisingl a body portion extending beneath .the lower face of the sash rail beyond the groove and having an upper tongue seated within the groove and also having marginal lip portions separated by LEWIS T.
